Comment (by conner_bw):

 Chiming in with a me too.

 If I apply this patch it fixes the issue:

 https://core.trac.wordpress.org/attachment/ticket/13340/13340.diff

 For obvious reasons, I won't patch `wp-includes/formatting.php`,
 WordPress must do it...

 Or, let us filter those strings? Example:


 {{{#!php
 $allblocks = apply_filters( 'autop_allblocks',
 'table|thead|tfoot|caption|col|colgroup|tbody|tr|td|th|div|dl|dd|dt|ul|ol|li|pre|form|map|area|blockquote|address|math|style|p|h[1-6]|hr|fieldset|legend|section|article|aside|hgroup|header|footer|nav|figure|figcaption|details|menu|summary'
 );
 $allblocks = '(?:' . $allblocks . ')';

 // ... snip ...

 // Replace newlines that shouldn't be touched with a placeholder.
 $newline_preservation_helper = apply_filters(
 'autop_newline_preservation_helper', 'script|style' );
 $pee = preg_replace_callback( '/<(' . $newline_preservation_helper .
 ').*?<\/\\1>/s', '_autop_newline_preservation_helper', $pee );
 }}}
